If I could afford the high end gear I could afford not to be here on CN. So until I win the lottery.....

I went ahead and took the leap, telescopes.com seems pretty reputable, so if I get a bad set I'll just return them. If they're OK, it'll be a great deal at $69 with free shipping and no tax. Wish me luck...

it seems most here in favore of the zhumells dont understand my point, all im saying is... i personally wouldnt buy them, having bought "bottom end" gear before(not just bins)even if they were "useable" this is my hobby and i want to enjoy it fully. as to the remarks ("if i could afford top end gear i wouldnt be here")doesnt make the bottom end gear any better and potentually could meen you waste even more money as price isnt allways a good indicator of how good an item is, giving up the "free" and good advise here would seem a foolish thing to do even if you did win the lottery.
i supose in the end you have to ask your self "how much does it cost to make something properly?" and can i afford it? if not then you really nead to decide what your willing to put up with before spending your hard earned cash, i think theirs more to buying and owning bins than just seeing two merged magnified images through them, the quality of that image "counts" a lot to me and adds to the enjoyment and i guess after seeing that theirs no going back. i dont have any bins now after giving them away or selling them apart from a pair of japanese made vintage (fully coated only) "harmony" 7x50's that cost me ALL OF £16! and im still saving to find a modern fully multi coated pair that match them in optical and build quality does that make me a "snob"... i wouldnt take £30 out of my savings for a pair of "new" 20x80 bins of the lowest quality when for much cheaper i can acquire second hand and older bins of far better even top quality if im prepared to wait and look around a bit... so having not much cash is no excuse to buy rubbish ...is it, how ever lack of patients i suppose is nowadays.... man like i said buy what you want, all im doing is offering a diferent viewpoint. and if you can get your money back, go ahead,... knock yer self out!

Relax Mark. You have made your points, and most (and probably all here) perfectly understand where you are coming from.
But you dont have to take it as a personal affront when peoples' choices dont coincide with yours. You have made your choice, have given us good reasons why you did so, and it appears that you are happy with it.
Others (me included) have made different choices, like you are also aware of pros and cons of the choices made, and it appears that we are happy with it.
So lets be happy for each other also. I am happy (and proabaly all here are too) that you chosen to take the road of patience and will be delighted when you do acquire those binoculars that give you views that delight you. And please share in our happiness to have taken the road in binoculars that gives us views that delight us.

The best we can do is help folks make an informed decision.
The buyers reasons and motivation are their own and I'm sure they will change over time as circumstances permit.
So you do what ya gotta do.

Hi everyone,
I have decided to try these binos out and ordered them today. I hope they will serve my needs. Does anyone know what the FOV is for these? I have looked through the info on the web page but I haven't come across it. I would like to use this info in Starry Nights Pro and Astroplanner equipment list.
thanks,

Just remember, from all the testing done on binoculars by EdZ, the "advertised" FOV is sometimes different from the "real" FOV, but, at least you have a "general" idea.

Mine arrived today and seem great thus far. It's still daylight, but looking at the neighboring mountains and the moon is pretty impressive. As far as looking for problems, what should I be looking for?

DON'T LOOK for problems! If any are present, they will find you.

I have a Denk 2 that has provisions too move the diopters to collimate them.Bill Mitchell
I'm not trying to be difficult, but what if the binocular is collimated via the traditional eccentric-ring method, such as in the Fujinon MT and FMT series or the Nikon Astrolux or Prostar, or perhaps the old Swift Stormking?BillC
Does the eccentric-ring method not change the position of the diopters? I don't understand what the difference would be.If there is a difference, they both don't apply to these binoculars the diopters cannot be user ajusted. I assume thats why they cost $69.00

Hi Bill:
It would seem we are talking about two different animals. I was speaking of binoculars and apparently you are speaking of a binocular viewer.
In what I was talking about, neither an eccentric ring set up at the objective (the vast majority) or the ocular (the vast minority) will change the “diopters” in the original sense of the word—that being a measurement of the displacement of a focus or focal point.
I believe that when you were talking about “diopters,” you were speaking of the physical diopter MECHANISMS. Through that method, classical collimation is not likely to be obtained—too many variables. However, you most certainly can achieve a conditional alignment, which is, AT ONE IPD, tantamount to true (classical) collimation.
I don’t use bino viewers. However, you not only have freedom in the eccentricity of the diopter rings, but in the eccentricity of each eyepiece as well.
IF you use the same EPs, AND if you return again and again to the same IPD, you should be sitting pretty, unless the prisms have some lost motion. In that case, it would be the proverbial “krap shoot.” (misspelled to keep the naughty gnome happy)
If I misunderstood you to start with, I certainly apologize; I could have sworn you were speaking of binoculars.
Have a great evening.
Cheers,
Bill

If one removes the eyepieces from a binocular viewer and reverses it, it can be precisely adjusted(if necessary) on a distant target, perhaps with the aid of a small auxiliary telescope or one side of a binocular telescope ( a "binocular"). It can then be used, again in the reversed position, without eyepieces, as a rather narrow field comparator to help in adjustment into "conditional collimation" a binocular telescope.
